If, by saying "go off", you mean that a gfci switches off the supply of electricity, the reason is that it has been made to do this whenever there is:
If any GFCI does not reset when you press its 'Reset' button then you will have to find out:
Only after a fault has been fixed will the GFCI reset when you press its 'Reset' button. Then all outlets and appliances connected to it will once again receive a supply of electricity.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

GFCI protection is required for most outdoor receptacles, bathroom , garage wall outlets, kitchen, and all receptacles in crawl space.
faulty wiring or you are accidentally hitting the switch and not realizing it
its off ! Or it is about to go off (sour) and the heat of the tea has set the process "over the edge".
A car alarm can go off with no one even near it. A bad earthing point or voltage change can make it go off. The sensor on the alarm itself may be too high which will cause it to go off with the lightest of touch.
it could be a ghost
1. Check with local regulation , authorities. Go by the local law or regulation. 2. If the application is in wet area, risk of ground fault is more, hence go for GFCI.
Generally, no.

Most definitely. GFCI receptacles have a test buton, and should be tested regularly. you can also buy inexpensive plug-in testers at most home centers and electric supply houses.
In a very real sense, a "ground fault" cannot come from the neutral side, since, if your wiring is performing as designed, there should be little potential between the neutral and ground. A ground fault is said to occur when the current OUT, through the "hot" side is not equal to the current BACK, through the neutral, meaning that current is leaking to somewhere else... such as through your body. Having said all that, it is certainly possible that you could cause a GFCI to trip by introducing current to the neutral from a circuit that does not go through the GFCI breaker; but that would involve non-standard wiring practices.
